The stampede to advertise on social networks is behind ZenithOptimedia’s forecast that display will soon be the internet’s top type of advert. Display will rise from 36% of internet spend in 2011 to 41% in 2014. Already, 25% of advertising money is online in Denmark, Norway, South Korea, Sweden and the UK. ZenithOptimedia says Canada, China, Norway, South Korea, Sweden and the UK will hit 30% by 2014.
